29 Claims.

This invention relates to devices for guiding and controlling glass or transparent panels of windows, particularly windows of automobiles in which the transparent panels or panes are adapted to be raised and lowered, usually through the medium of some suitable window regulator mechanlsm operable from the inside of the automobile body. The invention is particularly useful in connection with windows of vehicle bodies, such as automobile bodies, wherein the window opening is controlled by means of a pivoted transparent panel and a vertically slidable transparent panel cooperable in fully raised positions to close the window opening.

An object of the invention is to provide improved means for guiding and controlling the sliding panel during its upward and downward movements so that the panel will travel more easily and with less frictlonal resistance while at the same time it will be held rmly in substantially all positions thereby minimizing vibrational movements thereof during the travel .of the vehicle.

A further object is to provide an improved ventilating window structure of the type having a pivoted panel and a sliding panel cooperable, when raised, to close the window opening and in which the sliding panel at its normally unsupported end adjacent the pivoted panel is guided into and out of the window well by ilxed guides' guide for the sliding panel, particularly a sliding panel of a Ventilating window of the foregoing type, vthe guide being adapted to be fixed within the window well and comprising aV relatively? short upper channel section of materially less length than the height of the panel and through which the metal bound edge of the Panel passes during its vertical travel and also comprising a relatively long guide, preferably of a length atleast as great as the height of travel of the panel',

slidingly receiving a projecting member, stud or the like secured to the lower edge of the panel adjacent said short upper channel section, the construction anclg'v operation being such that one end, such as the forward end, of the sliding panel is guidingly supported by said compound guide at separate points increasingly spaced in a ver- Y tical direction as the panel is lowered into the window well. Hence, by virtue of ,the improved construction of the compound guide and asso- (Cl. 296-445) l l 'ciated parts the normally unsupported` vedge of the panel is held against tilting and vibrational movements in a better and more eifectual manner, while at the same time the amount oi frictional resistance tothe operation of the panel is materially decreased thereby enabling the window to be raised and lowered with a minimum of effort.

In accordance with conventional automobile body construction the door or other side wall portion of the body is provided with'va window opening adapted to be closed or partially so'by means of a glass panel which may be lowered into a well below the window opening. In conventional practice `the front' and rear upright edges rof the glass panel are guided within the Well by means of channels lined with felt or equivalent material which receive and embrace the edges of the glass. To provideproper guiding of the glass within the window'w'ell and also to prevent rattling of the glass when partly or fully lowered itA is necessary in practice to provide a relatively snug fit of the edge of the glass in the felt or otherwise lined channel. vOwing to allowable tolerances in production and manufacturing variations or inaccuracies it has ben diicult to secure uniformly the desired fit of the edges of the If the glass glass within the guide channels. fits tootightly excessive friction is set up rendering it .more'difllcult to raise and lower thelglass and placing `undue strain on the regulator mech-Y anism, and since this condition occurs frequently in production it has been necessary to make the `window regulators stronger than need be,.

thereby increasing their cost. Since these felt lined channels, mounted in the window well,"are exposed to the weather and become wet as a re- `sult of waterrunning down the edges of the window I opening into the channels during rainy f weather or when the car is washed, even greater effort is required under such conditions to operate the window.

Itwill thus be seen that an accurate slidingl t ofthe glass within the guide channels is extremely difficult Yto obtain owing to variations of increased labor expense due to diiliculties in installing the glass therein on the assembly linie,l

An object of the present invention is to provide improved means for guiding the'window glass into and out of the window Well, permitting easy and economical installation of the glass. which means is relatively simple in construction, capable of effecting substantial savings in material and labor costs, more efliicent in use, and permitting the use of window regulators of less expensive construction.

A further object is to provide an improved window glass guide which eliminates the necessity of directly guiding the uprightl edge of the glass into and out of the window well,wl1ich provides more accurate control of the glass regardless of manufacturing variations, and which automatically accommodates or compensates` for such variations without appreciably increasing the ellort reqiured to movethe glass-'up and down. i

Another object is to provide guiding means at, but independent of, the opposite upright edges of the glass which permits and also takes up slight end play, i. e. edgewise movements of the glass in its plane, frequently caused by the throw of the window regulator or resulting from small inaccuracies in'the window regulator construction.

Another object of the invention is to provide an improved channel member for retaining the lower edge of the glass, in whichsuch channel member may embody detachably connected sections and may have one or a plurality of devices at either or each end thereof adapted to travel up and down within a fixed guide or guides in thefwindow well, and embodying yielding means to hold the glass against rattling and also to take up or permit slight movements of. the glass. More particularly such device preferably comprises a stud slidable vertically in the guide and a spring pressed compression member slidable on the `stud against the guide,v an advantageous feature being that the window glass can,y byy virtueof the linvention, be guided substantially or'nearly in line with the upright edge of the glass independently of this edge and without interference therewith.

Al further cbjectof the invention is to provide improved guide means for the sliding transparent panel, particularly a sliding panel of a Ventilating window of the foregoing type, wherein there is provided in the window welladjacentopposite upright edges of said sliding panel a pair of upright channel'guides xed within the window well and which are engaged byprojectingguide devices carried by the glass retainer channel at the lower edge of the window glass, saidchannei guides being arranged to guide the sliding panel or window glass within the window well Awholly independently of the upright edges of the panel or glass, and the front guide which is adjacent the line of juncture between the pivoted and sliding glass panels being located forwardly of the edge of the sliding panel and engaged by vertically spaced guide devicescarried by the glass retainer channel. y

Before explaining in detail the present invention it is to be understood that the invention is not limited in its application to the details of construction and arrangement of parts illustrated in the accompanying drawings, since the invention is capable of other embodiments and of being practiced or carried out in various ways. Also it is to be `understood that the phraseology or terminology employed herein is for the purpose of description and not of limitation, and it is not intended to limit the invention claimed herein beyond the requirements of the prior art.

In the drawings there are illustrated certain embodiments of the invention applied, by way of example, to an automobile door. It will be understood, however, that the embodiments herein exemplified may in part or in whole be utilized in.

other relations and in other structures. In Fig. 1 there is illustrated an automobile door A which may be a front door including a front sloping pillar I0 and a rear vertical pillar Il, the upper portion of the door being provided with a main window opening adapted to be closed by means of a vertically slidable glass or other transparent panel I2 and a swinging glass or other transparent panel I3. In the present instance `the panel I3, which is of the so-called wing type, is disposed at the` forward part of the window opening and the sliding panel I2 is disposed in rear thereof, and these panels are preferably arranged so that when in fully closed positions they extend in the same or in substantially parallel planes and cooperate together to close the main window opening. The wing type panel I3 may be pivoted at points I3a so as to swing horizontally about an up and down axis. The sliding panel I2 has secured to the upright edge thereof adjacent the panel I3 a metal binding strip or bar I4 in the form of a channel embracing the said edge of the panel I2 and fixed thereto. As shown in Fig. 4, the metal binding strip oi bar I4 has a projecting l Y flange Ila which forms an overlap for the adjacent upright edge of the wing I3 when swung into closed position.

It will be understood that the term glass is used herein in a generic sense and is intended to comprehend any panel regardless of material movable up and down to close or open a window y l so as to permit assembly of the window regulator. These sections I6, if desired, may be made in one length with a notch or aperture through the bottom thereof corresponding to the space between their inner ends, shown in Fig. 1, to permit passage of one of the regulator studs Il when the window glass is lowered into the window frame and assembled with the regulator in the extreme lowered position of the latter.v The rail sections I6 are conventionally formed to provide llongitudinal guideways for the headed studs,

rollers or the like I1 carried at the outer end of the window regulator, the studs travelling or sliding longitudinally back and forth in the guide- Ways of sections I6 when the window is raised and lowered. f

Any suitable window regulator may be utilized and in the present instance a regulator of the parallel arm type is in pant shown for the purpose of providing through the medium of th spaced projecting studs I'I a support for the window panel I2 at two horizontally-spaced points. A single arm regulator or other type of two-arm regulator may be used if desired. The illustrated regulator comprises a horizontal bar I8 to which 3;, the studs I1 are secured as by riveting, this bar having a depending angular extension I8a. The

parallel varm regulator, well known in the art,

comprises a pair of parallel swinging arms I9 and 20 pivoted at their outer ends at vertically spaced `points 2l and 22 to the bar I8 and its extension I8a. A further detailed description oi the parallel arm regulator is not deemed necessary herein as it may be of conventional construction comprising the usual mounting plate secured to the inner metal door panel 24 to which mounting plate the inner ends of the arms I9 and 20 are pivoted at vertically spaced points corresponding to the spacing of the points 2I and 22. The arms I9 and 20, as is well known, areswung through the medium of suitable gearing on the mounting plate operated from a crank handle mounted at the inner side of the ldoor or body. I

The forward upright edge of the sliding panel I2, i. e. the edge to which is secured the metal. channel strip or bar I4, is guided during its up and d-own travel by means of what isv herein termed for convenience a compound guide, see Figs. 2 and 4. This guide, in the present embodiment, includes an upright or substantially vertical supporting channel 23. This main supporting channel 23 is adjustably secured at the inner metal door or body panel 24 of the body through the medium of a channel shaped bracket 425. The outer central web 25a, of this bracket i's spot welded to the vertical side 23a of the main channel and has out-turned anges 25h provided with suitable screw bosses for the reception of adjusting screws 26 passing through slots 21 in Ithe inner door panel 24. By means of adjusting screws 26 and slots 21 the bracket 25 and hence the main channel 23 may be adjusted in a longitudinal direction. It will be noted that the main supporting channel 23 receives the bar I4v carried by the forward edge of the sliding panel I2.' 'Ihis bar I4 has a depending extension I4b below the ed upon rthe supporting channel 23.

end of Ithe channel 23lwhen the panel I2 is in its fully raised position as shown in Figs. l and 2.

Securedas by spot welding to the backface of 'the glass retainer channel I5, and forwardly of the rail members I6, is an angle bracket or angular gusset type plate 28. The forward upright edge of this bracket or plate is offset or embossed at 28a to extend into the yback side of the channel bar I4 below the window panel I2, the forward edge of ithe plate 2B being flanged at 28h to fit within the channel I4, as shown in Fig. 4, the parts 28a` and 28h being spotiwelded to the bar I4. The flange ZBbfextends somewhat Abelow the lower end 'of the window bar extension I4h,

see Fig. 2, terminating in a return bent flange 28o secured to the adjacent `portion'of the plate 28 for reinforcement. Spot welded to the forward face of the flange 28h and below the lower end of the extensions I4b of the bar I4 is a spacer vblock or plate 29 and to .the parts 29 and 28h is riveted the reduced Aend of the shank 30a of a stud 30, see Fig. 4. Slidingly mounted upon the stud 30 is a substantially conical Washer or compression member 3l preferably of cup-like construction engaged by a compression spring 32 surrounding the shank 30a. The-washer 3l Ahas a central cylindrcal sleeve, as hereinafter described, terminating in a flange movable toward `and from a rear shoulder of the stud 30 thereby anchoring the washer at its forward .limit of travel and perchannel section, as shown in Fig. 4, extending from the supporting channel 23 to a point well down into the window well below vthe main window opening, this channel guide 33 havingsucient length to guide the panel I2 within the well throughout'its vertical range of movement. The

channel guide 33 aty its upper end is, in the present instance. -telescoped into the lower end of the supporting channel 23 and the forward central web of the channel guide 33 abuts against the inner face of Ithe forward central vertical web 23o of the channel 23, and the channel 33 is spot Welded to the channel 23 substantially in the position shown in Fig. 2. It will be noted tha-t the channel guide 33 is offset forwardly out of ver.

tical alinement with the bar I4 on the forward edge of the sliding panel I2. 33 preferably faces rearwardly in the same direction -as the main channel 23 andv is formed, as shown in Fig. 4, with reversely tapered portions The channel 'guide' providing a constricted neck 33a Slidingly re-VV ceiving the stud 30 and flaring track portions slidingly engaged by the crowned or convex face of the Washer or compression member 3I. yIt will be seen that the stud may slide in and out within ythe guideway 33a of the channel 33 thereby permitting compensationV for variations in the travel of the glass.

The compound guide lalso includes, in addition to the relatively long channel guide 33, a relatively short channel guide 34 which is also mounttively sho/'rt channel or guide 34 is shown in Fig. i 8 and preferably comprises -a detachable insert member which may be readily installed-,within the channel y23 after 'the installation of the window panel I2 and the guide stud 30 with its associated partswithin the channel 33.

The insert The relachannel guide 34 may comprise a channel having at its upper end a depth substantially correspondlng to the supporting channel 23. The forward central web 34a of this channel terminates at 34h and is cut away along the lines 34o and 34d to provide a notched-out portion shaped to fit around or straddle the upper telescoped end of the channel guide 33. The side ilanges of the channel section 34 at the rear inner edges thereof are provided with liners of felt or other material 35. These liners may comprise strips which -are folded around the edges of the channel 34 as at 35a and cemented or otherwise secured thereto., The insert channel member 34 is attached within Ithe main channel 23 and held in place by means of a pair of bent-up hook-like tabs 31 which hook into notches in the lower edges of the side flanges 23a and 23h of the channel 23. The member 34 is also secured in place by means of an upper tongue or tab 33 adapted to be bent down over the upper edge of the web 23e of the supporting channel 23, as shown in Fig. 2. From the foregoing it will be seen that the supporting channel 23 with the insert channel 34 provides a relatively short substantially vertical guide for ythe bar I4 along the forward edge of the panel I2. This bar travels through the insert channel 34 and engages the liners 35. Thus, when the sliding panel I2 is in its fully raised position the depending extension I4b of the bar I4 at the forward edge of this panel lies within the channel section 34 in snug engagement with the liners 35 thereof. At the same time the guide stud 30 and compression member 3l engage the channel guide 33 which is offset forwardly of the bar I4 and its extension. At this time it will be seen that the guide stud 30 extends beneath and across the lower end of the bar extension I4b into sliding engagement with the relatively long channel guide 33. As the window panel is lowered the amount of guiding engagement of the bar I4 with the compound guide is limited to the height of the insert channel section 34 and hen-ce as this glass is lowered it will be guidingly supported at separate points in substantially the same vertical plane which points are increasingly spaced in ra vertical direction as the panel is lowered in the window well. Thus, when the panel I2 is dropped into the well to its fully lowered position the forward edge thereof will be guided at its upper end through engagement with the short channel section 34 and its lower end will be guided through engagement of the stud and washer 30, 3l with the channel guide 33 at or near the bottom of the window well. Hence, the effective guiding support of the forward edge of the sliding panel I2 improves as the panel I2 is lowered from its top position since the guides 34 and 33 move further apart as the window is lowered, but at the same time the frictional resistance to the movement of the window panel remains at all times substantially the same.

Referring particularly to Figs. 3 and 5 to 7 inclusive, the rear upright edge I2a of the glass panel I2 may be guided within the window opening through the medium of a felt or otherwise lined channel 50 which is designed to embrace the edge of the glass when the glass is fully raised. This channel 50 preferably terminates at or slightly below the lower edge of the window opening as indicated at 50a. Within the well below the window opening the window panel I2 is guided in its up and down path of movement substantially entirely through guiding means which is operative independently ofthe edge Ila.

For 'this purpose there is mounted within the window well an upright or vertically extending nxed guide member 33, which may lbe substantially or approximately beneath the upright edge of the glass panel. In Figs. 6 and 7 the guide is illustrated as arranged substantially in vertical alinement with the upright edgev I2a of the glass. The channel guide 33 may be spaced inwardly from the base IIa of the pillar II and supported therefrom through the medium of angle brackets 33 spot welded to the pillar and to the channel guide 33. The guide 33 extends well down into the window well a sufficient distance to accommodate the full range of vertical travel of the panel I2.

The glass retainer member or bar I5 is provided at its rear end with a projecting guide member or device adapted to cooperate with the vertical guide 33. Spot welded to the base of the retainer channel I5, as seen in Figs. 3 and 7, is the horizontal flange 43a of an angle bracket 43. To the vertical flange 40h of this bracket is riveted a-t 44 the reduced end 43 of a cylindrical stud 4I. The end of this stud has a head 42 forming an annular `shoulder against which a cushion sleeve 45 bears. The sleeve 45 may be of resilient rubber or other relatively compressible non-metallic material and embraces the stud 4I, see Fig. 5. Surrounding the sleeve 45 and slidable thereon is the cylindrical sleeve of a compression member 46. This member terminates in an annular infturned ilange 41 slidable freely over the stud 4| and limited in its outward movement by engagement with the end of the sleeve 45. 'The compression member 43 may be a die casting and is provided with a convex or dared annular washer portion 43 providing an annular cup-shaped recess at its back facefor receiving and retaining one end of a compression spring 49, the opposite end of |the spring bearing against theflange 4Ib of the bracket v4l). Thus, the compression member 43 may slide longitudinally on the stud 4I upon the cushioning sleeve 45 and against the eifort of the spring 43 which at all times is under compressi-on.

The guide member 33 is in the form of a channel having a base 33a and parallel side walls terminating in inwardly converging portions 33h. This guide member is preferably in the form of a rolled section and the converging portions 33h terminate in a constricted neck portion 33d, the metal thence being bent outwardly to provide diverging flared track portions 33e. When the window is installed the guide device 4|, 43 preferably has a sliding fit in two directions against the constricted neck portion 33d, i. e. vertically and longitudinally. The crowned face of the washer portion 43 contacts the flaring or diverging portions 38e and at this time the spring 43 is under compression, thereby spacing the flange 4l from the shoulder formed bythe inner end of the sleeve 45. This clearance space is normally sufficient so as to permit slight longitudinal sliding of the compression member 46 yon the sleeve 45 during operation of the window to compensate for slight variations in the construction of the associated operating and guiding members for the window. As shown in Fig. 6, when the window panel I2 is lowered into the well the edge |2a thereof is permitted to pass through the channel guide 38 between the opposed portions 33d thereof. It will be understood, however, that the channel guide 33 may be positioned at a greater distance from the` edge of the winguide without 'passing therethrough:

In Figs. 9 and 10 there is illustrated'arno'diiled` construction wherein theiguide channel 33 is re- 5 placeclI-bycmeans of a channel guide 5|' which may be secured'and, located in the samemanner through .the medium of the upper and lower angle brackets 39. Each channel guide 5i has a bot'- l I scribedthe' lower guide device 30; 321 carried b'yv i the'bracket i5 may be made detachable, if 'dei l0 rsired,`through the medium of a lock nut engage- I tom wall Sib and-parallel sidewalls .'Iidwhich l terminate in outer flared traclc portions Bic.-

There may be mounted upon the lbracket flange b a guide stud 52 having a cylindrical head 53,

the stud being riveted at 54 to the bracket flange. j Mounted upon the head 53 of the stud `is aA com-- l pression or cup-shaped washer .'95 which mayj also be in the form 'of a die casting. This compression member 55'has a convex orcrowned face engageable with' the track portions Mc'and is centrally recessed to provide a cylindrical guide' portion 56 slidable upon the head 53 and termi; natlng in an annular stop flange 51 'movable toward and from the 'shoulder formed by the.` head 53. A kcompression springy 5l, similar to spring 49, is interposed between the washerv 5land the bracket flange 40h. In this instance 'the channelway in member 5I is somewhat wider than the channelway in the channel guide 33 and flared contact surfaces Bic.

Referring to the embodiment iiiustrated in rissa- 11 to 13 inclusive, the'glass retainer vchannel Il is provided at'its forward end adjacent theloint y 3l between the glass panels I2 and I3 with a bracket Ol similar to the bracket 28 of the 'previous' em` bodiment.

Mounted upon the lvertical, flange lb below the leg Hb are a pairv of vertically spaced guide devices each comprising ,a guide stud 30, compression member or' washer 3| and compression spring 32, corresponding to the guide device' illustratedin Figs. 1v to 4 inclusive. vIf desired, to facilitate assembly of the window panel, the

lower guide device maybe made detachable fromv the bracket flange o. In such instance, in-v stead 'of the stud being rivetedto the ilangein 5d the manner illustrated at' 30h, thevlower stud 3l will extend through a hole in the fiangeb and its projecting rend provided withrscrew threads for engagement by a lock nut. lock nut the lowerstud30 together withV the m'washer'and spring may be detached from the flange 30h.
